Tags: ,

Afternoon of September 29 – at the ERM Symposium #ERMSYM

Bad risk culture has been blamed as the ultimate source of problems that have caused gigantic losses and corporate failures in the past 10 years. But is that a helpful diagnosis of the cause of problems or just a circular discussion? What is risk culture anyway? Is it a set of practices that a company can just adopt or does culture run deeper than that? How does risk culture vary between countries and continents? How do risk cultures go bad and can they be fixed? This is, of course, a discussion of the human side of Enterprise Risk Management. 

This half-day seminar (1 – 4:30 p.m.) will draw together materials from business organizational theorists, anthropologists, regulators, rating agencies, investors, corporations, insurers and auditors to help define risk culture and diagnose problem causes. The objective is to provide the attendees with multiple perspectives on risk culture to help them to survive and thrive within the potentially multiple risk cultures that they find themselves operating alongside – or against. In addition, the speakers will draw upon their own experiences and observations to provide a number of practical examples of how risk cultures can and do go wrong. This discussion may help you to identify the signs of devolving risk culture if they start to appear in your organization. Finally, the difficult topic of fixing a bad risk culture will be discussed. That part of the discussion will help attendees to attain a realistic perspective on that extremely difficult process. 

The seminar will be presented by three speakers from very diverse backgrounds. Andrew Bent, Risk Coordinator for Suncor Energy Inc. has also worked in multiple levels of government in New Zealand and Canada. Bent has co-authored several articles and papers on strategic risk assessment and the use of root cause analysis in risk management. Carol Clark is Senior Policy Advisor at the Federal Reserve Bank of Chicago where she has most recently been focused on operational risk issues associated with high speed trading. Her research has been published in the Journal of Payment Systems Law, the Federal Reserve Bank of Chicago’s Chicago Fed Letter and Economic Perspectives as well as Euromoney Books. Dave Ingram is Executive Vice President at Willis Re where he advises insurers on ERM practices. Ingram has worked extensively with both Life and Property and Casualty insurers on various aspects of risk management over the past 30 years. He has recently co-authored a series of articles and papers on risk culture and has had a number of experiences with the risk cultures of over 200 insurers.

The History of Risk Management

Please find a new permanent page on RISKVIEWS – The History of Risk Management.  It is a simple list of major historical events that are important to Risk Management and ERM as it is practiced today.  This list was compiled with the help of INARM

Risk Management development has not followed a particularly straight line.  Practices have been adopted, ignored, misused.  Blow up have happened.  Some of those blow ups are mentioned on another page in RISKVIEWS – Risk Management Failures

But Risk Managers have learned from those blow ups and the next generation of Risk Management programs incorporated those learnings. 

The most important thing to know about risk management that we have learned from history is that risk management must be practiced in earnest.  No amount of good talks or fancy charts will take the place of roll up your sleeves and do it risk management.  Promoting that sort of Risk Management is the objective of this Blog. 

 

 

Too Much Risk

Risk Management is all about avoiding taking Too Much Risk.

And when it really comes down to it, there are only a few ways to get into the situation of taking too much risk.

  1. Misunderstanding the risk involved in the choices made and to be made by the organization
  2. Misunderstanding the risk appetite of the organization
  3. Misunderstanding the risk taking capacity of the organization
  4. Deliberately ignoring the risk, the risk appetite and/or the risk taking capacity

So Risk Management needs to concentrate on preventing these four situations.  Here are some thoughts regarding how Risk Management can provide that.

1. Misunderstanding the risk involved in the choices made and to be made by an organization

This is the most common driver of Too Much Risk.  There are two major forms of misunderstanding:  Misunderstanding the riskiness of individual choices and Misunderstanding the way that risk from each choice aggregates.  Both of these drivers were strongly in evidence in the run up to the financial crisis.  The risk of each individual mortgage backed security was not seriously investigated by most participants in the market.  And the aggregation of the risk from the mortgages was misunderestimated as well.  In both cases, there was some rationalization for the misunderstanding.  The Misunderstanding was apparent to most only in hindsight.  And that is most common for misunderstanding risks.  Those who are later found to have made the wrong decisions about risk were most often acting on their beliefs about the risks at the time.  This problem is particularly common for firms with no history of consistently and rigorously measuring risks.  Those firms usually have very experienced managers who have been selecting their risks for a long time, who may work from rules of thumb.  Those firms suffer this problem most when new risks are encountered, when the environment changes making their experience less valid and when there is turnover of their experienced managers.  Firms that use a consistent and rigorous risk measurement process also suffer from model induced risk blindness.  The best approach is to combine analysis with experienced judgment.

2.  Misunderstanding the risk appetite of the organization

This is common for organizations where the risk appetite has never been spelled out.  All firms have risk appetites, it is just that in many, many cases, no one knows what they are in advance of a significant loss event.  So misunderstanding the unstated risk appetite is fairly common.  But actually, the most common problem with unstated risk appetites is under utilization of risk capacity.  Because the risk appetite is unknown, some ambitious managers will push to take as much risk as possible, but the majority will be over cautious and take less risk to make sure that things are “safe”.

3.  Misunderstanding the risk taking capacity of the organization

 This misunderstanding affects both companies who do state their risk appetites and companies who do not.  For those who do state their risk appetite, this problem comes about when the company assumes that they have contingent capital available but do not fully understand the contingencies.  The most important contingency is the usual one regarding money – no one wants to give money to someone who really, really needs it.  The preference is to give money to someone who has lots of money who is sure to repay.  For those who do not state a risk appetite, each person who has authority to take on risks does their own estimate of the risk appetite based upon their own estimate of the risk taking capacity.  It is likely that some will view the capacity as huge, especially in comparison to their decision.  So most often the problem is not misunderstanding the total risk taking capacity, but instead, mistaking the available risk capacity.

4.  Deliberately ignoring the risk, the risk appetite and/or the risk taking capacity of the organization

A well established risk management system will have solved the above problems.  However, that does not mean that their problems are over.  In most companies, there are rewards for success in terms of current compensation and promotions.  But it is usually difficult to distinguish luck from talent and good execution in a business about risk taking.  So there is a great temptation for managers to deliberately ignore the risk evaluation, the risk appetite and the risk taking capacity of the firm.  If the excess risk that they then take produces excess losses, then the firm may take a large loss.  But if the excess risk taking does not result in an excess loss, then there may be outsized gains reported and the manager may be seen as highly successful person who saw an opportunity that others did not.  This dynamic will create a constant friction between the Risk staff and those business managers who have found the opportunity that they believe will propel their career forward.

So get to work, risk managers.

Make sure that your organization

  1. Understands the risks
  2. Articulates and understands the risk appetite
  3. Understands the aggregate and remaining risk capacity at all times
  4. Keeps careful track of risks and risk taking to be sure to stop any managers who might want to ignore the risk, the risk appetite and the risk taking capacity

Insurers need to adapt COSO/ISO Risk Management to achieve ERM

Both the COSO and ISO risk management frameworks describe many excellent practices.  However, in practice, insurers need to make two major changes from the typical COSO/ISO risk management process to achieve real ERM.

  1. RISK MEASUREMENT – Both COSO and ISO emphasize what RISKVIEWS calls the Risk Impressions approach to risk measurement.  That means asking people what their impression is of the frequency and severity of each risk.  Sometimes they get real fancy and also ask for an impression of Risk Velocity.  RISKVIEWS sees two problems with this for insurers.  First, impressions of risk are notoriously inaccurate.  People are just not very good at making subjective judgments about risk.  Second, the frequency/severity pair idea does not actually represent reality.  The idea properly applies to very specific incidents, not to risks, which are broad classes of incidents.  Each possible incident that makes up the class that we call a risk has a different frequency severity pair.   There is no single pair that represents the class.  Insurers risks are in one major way different from the risks of non-financial firms.  Insurers almost always buy and sell the risks that make up 80% or more of their risk profile.  That means that to make those transactions they should be making an estimate of the expected value of ALL of those frequency and severity pairs.  No insurance company that expects to survive for more than a year would consider setting its prices based upon something as lacking in reality testing as a single frequency and severity pair.  So an insurer should apply the same discipline to measuring its risks as it does to setting its prices.  After all, risk is the business that it is in.
  2. HIERARCHICAL RISK FOCUS – Neither COSO nor ISO demand that the risk manager run to their board or senior management and proudly expect them to sit still while the risk manager expounds upon the 200 risks in their risk register.  But a highly depressingly large number of COSO/ISO shops do exactly that.  Then they wonder why they never get a second chance in front of top management and the board.  However, neither COSO nor ISO provide strong enough guidance regarding the Hierarchical principal that is one of the key ideas of real ERM.    COSO and ISO both start with a bottoms up process for identifying risks.  That means that many people at various levels in the company get to make input into the risk identification process.  This is the fundamental way that COSO/ISO risk management ends up with risk registers of 200 risks.  COSO and ISO do not, however, offer much if any guidance regarding how to make that into something that can be used by top management and the board.  In RISKVIEWS experience, the 200 item list needs to be sorted into no more than 25 broad categories.  Then those categories need to be considered the Risks of the firm and the list of 200 items considered the Riskettes.  Top management should have a say in the development of that list.  It should be their chooses of names for the 25 Risks. The 25 Risks then need to be divided into three groups.  The top 5 to 7 Risks are the first rank risks that are the focus of discussions with the Board.    Those should be the Risks that are most likely to cause a financial or other major disruption to the firm.   Besides focusing on those first rank risks, the board should make sure that management is attending to all of the 25 risks.  The remaining 18 to 20 Risks then can be divided into two ranks.  The Top management should then focus on the first and second rank risks.  And they should make sure that the risk owners are attending to the third rank risks.  Top management, usually through a risk committee, needs to regularly look at these risk assignments and promote and demote risks as the company’s exposure and the risk environment changes.  Now, if you are a risk manager who has recently spent a year or more constructing the list of the 200 Riskettes, you are doubtless wondering what use would be made of all that hard work.  Under the Hierarchical principle of ERM, the process described above is repeated down the org chart.  The risk committee will appoint a risk owner for each of the 25 Risks and that risk owner will work with their list of Riskettes.  If their Riskette list is longer than 10, they might want to create a priority structure, ranking the risks as is done for the board and top management.  But if the initial risk register was done properly, then the Riskettes will be separate because there is something about them that requires something different in their monitoring or their risk treatment.  So the risk register and Riskettes will be an valuable and actionable way to organize their responsibilities as risk owner.  Even if it is never again shown to the Top management and the board.

These two ideas do not contradict the main thrust of COSO and ISO but they do represent a major adjustment in approach for insurance company risk managers who have been going to COSO or ISO for guidance.  It would be best if those risk managers knew in advance about these two differences from the COSO/ISO approach that is applied in non-financial firms.

Setting your Borel Point

What is a Borel Risk Point you ask?  Emile Borel once said

“Events with a sufficiently small probability never occur”.

Your Borel Risk Point (BRP) is your definition of “sufficiently small probability” that causes you to ignore unlikely risks.

Chances are, your BRP is set at much too high of a level of likelihood.  You see, when Borel said that, he was thinking of a 1 in 1 million type of likelihood.  Human nature, that has survival instincts that help us to survive on a day to day basis, would have us ignoring things that are not likely to happen this week.

Even insurance professionals will often want to ignore risks that are as common as 1 in 100 year events.  Treating them as if they will never happen.

And in general, the markets allow us to get away with that.  If a serious adverse event happens, the unprepared generally are excused if it is something as unlikely as a 1 in 100 event.

That works until another factor comes into play.  That other factor is the number of potential 1 in 100 events that we are exposed to.  Because if you are exposed to fifty 1 in 100 events, you are still pretty unlikely to see any particular event, but very likely to see some such event.

Governor Andrew Cuomo of New York State reportedly told President Obama,

New York “has a 100-year flood every two years now.”
Solvency II has Europeans all focused on the 1 in 200 year loss.  RISKVIEWS would suggest that is still too high of a likelihood for a good Borel Risk Point for insurers. RISKVIEWS would argue that insurers need to have a higher BRP because of the business that they are in.  For example, Life Insurers primary product (which is life insurance, at least in some parts of the world) pays for individual risks (unexpected deaths) that occur at an average rate of less than 1 in 1000.  How does an insurance company look their customers in the eye and say that they need to buy protection against a 1 in 1000 event from a company that only has a BRP of 1 in 200?
So RISKVIEWS suggest that insurers have a BRP somewhere just above 1 in 1000.  That might sound aggressive but it is pretty close to the Secure Risk Capital standard.  With a Risk Capital Standard of 1 in 1000, you can also use the COR instead of a model to calculate your capital needed.

Key Ideas of ERM

Posted July 24, 2014 by riskviews

Tags: , ,

For a set of activities to be called ERM, they must satisfy ALL of these Key Ideas…

  1. Transition from Evolved Risk Management to planned ERM
  2. Comprehensive – includes ALL risks
  3. Measurement – on a consistent basis allows ranking and…
  4. Aggregation – adding up the risks to know total
  5. Capital – comparing sum of risks to capital – can apply security standard to judge
  6. Hierarchy – decisions about risks are made at the appropriate level in the organization – which means information must be readily available

Risk management activities that do not satisfy ALL Key Ideas may well be good and useful things that must be done, but they are not, by themselves ERM.

Many activities that seek to be called ERM do not really satisfy ALL Key Ideas.  The most common “fail” is item 2, Comprehensive.  When risks are left out of consideration, that is the same as a measurement of zero.  So no matter how difficult to measure, it is extremely important to really, really be Comprehensive.

But it is quite possible to “fail” on any of the other Key Ideas.

The Transition idea usually “fails” when the longest standing traditional risk management practices are not challenged to come up to ERM standards that are being applied to other risks and risk management activities.

Measurement “fails” when the tails of the risk model are not of the correct “fatness“.  Risks are significantly undervalued.

Aggregation “fails” when too much independence of risks is assumed.  Most often ignored is interdependence caused by common counter parties.

Capital “fails” when the security standard is based upon a very partial risk model and not on a completely comprehensive risk model.

Hierarchy “fails” when top management and/or the board do not personally take responsibility for ERM.  The CRO should not be an independent advocate for risk management, the CRO should be the agent of the power structure of the firm.

In fact Hierarchy Failure is the other most common reason for ERM to fail.

Is it rude to ask “How fat is your tail?”

In fact, not only is it not rude, the question is central to understanding risk models.  The Coefficient of Riskiness(COR) allows us for the first time to talk about this critical question.

332px-36_Stanley_Hawk

You see, “normal” sized tails have a COR of three. If everything were normal, then risk models wouldn’t be all that important. We could just measure volatility and multiply it by 3 to get the 1 in 1000 result. If you instead want the 1 in 200 result, you would multiply the 1 in 1000 result by 83%.

Amazing maths fact – 3 is always the answer.

But everything is not normal. Everything does not have a COR of 3. So how fat are your tails?

RISKVIEWS looked at an equity index model. That model was carefully calibrated to match up with very long term index returns (using Robert Shiller’s database). The fat tailed result there has a COR of 3.5. With that model the 2008 S&P 500 total return loss of 37% is a 1 in 100 loss.

So if we take that COR of 3.5 and apply it to the experience of 1971 to 2013 that happens to be handy, the mean return is 12% and the volatility is about 18%. Using the simple COR approach, we estimate the 1 in 1000 loss as 50% (3.5 times the volatility subtracted from the average). To get the 1/200 loss, we can take 83% of that and we get a 42% loss.

RISKVIEWS suggests that the COR can be an important part of Model Validation.

 Looking at the results above for the stock index model, the question becomes why is 3.5 then the correct COR for the index? We know that in 2008, the stock market actually dropped 50% from high point to low point within a 12 month period that was not a calendar year. If we go back to Shiller’s database, which actually tracks the index values monthly (with extensions estimated for 50 years before the actual index was first defined), we find that there are approximately 1500 12 month periods. RISKVIEWS recognizes that these are not independent observations, but to answer this particular question, these actually are the right data points. And looking at that data, a 50% drop in a 12 month period is around the 1000th worst 12 month period. So a model with a 3.5 COR is pretty close to an exact fit with the historical record. And what if you have an opinion about the future riskiness of the stock market? You can vary the volatility assumptions if you think that the current market with high speed trading and globally instantaneously interlinked markets will be more volatile than the past 130 years that Schiller’s data covers. You can also adjust the future mean. You might at least want to replace the historic geometric mean of 10.6% for the arithmetic mean quoted above of 12% since we are not really taking about holding stocks for just one year. And you can have an opinion about the Riskiness of stocks in the future. A COR of 3.5 means that the tail at the 1 in 1000 point is 3.5 / 3 or 116.6% of the normal tails. That is hardly an obese tail.

The equity index model that we started with here has a 1 in 100 loss value of 37%. That was the 2008 calendar total return for the S&P 500. If we want to know what we would get with tails that are twice as fat, with the concept of COR, we can look at a COR of 4.0 instead of 3.5. That would put the 1 in 1000 loss at 9% worse or 59%. That would make the 1 in 200 loss 7% worse or 49%.

Those answers are not exact. But they are reasonable estimates that could be used in a validation process.

Non-technical management can look at the COR for each model can participate in a discussion of the reasonability of the fat in the tails for each and every risk.

RISKVIEWS believes that the COR can provide a basis for that discussion. It can be like the Richter scale for earthquakes or the Saffir-Simpson scale for hurricanes. Even though people in general do not know the science underlying either scale, they do believe that they understand what the scale means in terms of severity of experience. With exposure, the COR can take that place for risk models.
